Intriguing properties exhibited by porous coordination polymers (PCPs) have been discussed for a very long time, and the peak of the journey has been reached. Many ways have been introduced side by side to explore in the domain of PCPs with further progress to achieve various functionalities. Multifunctionality by these types of frameworks is one of those interesting features which has also been challenged to produce proper frameworks for exhibiting multiple properties by a single structure. Thus, after judicial choice of two different types of ligands, three coordination polymers {[Cd(1,4-(2-Me)-bix)(glu)]·5(H₂O)}_n (1), {[Cd₂(1,4-(2-Me)-bix)(msuc)]·(H₂O)}_n (3), and {[Zn(1,4-(2-Me)-bix)(msuc)]·(solvent)_x}_n (4) have been synthesized and characterized. These three compounds along with one previously reported structurally similar complex {[Zn(1,4-(2-Me)-bix)(glu)]·4(H₂O)}_n (2) have been used to study gas sorption, electrical properties in dark and light, and luminescence. All the PCPs display different gas adsorptions (CO₂, N₂, H₂) and electrical conductance in both dark and illuminated conditions, which is an indication of multifunctionality shown by these structures. This designed structure and the measured properties of the synthesized complexes have been correlated with each individual framework of the four complexes based on the dicarboxylate flexibility/substitution and the size of the metal ion.

通过改变链长、二羧酸酯的柔韧性和金属离子的大小合成多功能多孔配位聚合物

多孔配位聚合物 (PCP) 表现出的有趣特性已经讨论了很长时间，并且已经达到了旅程的顶峰。并列引入了许多方法，以在 PCP 领域进行探索，并在实现各种功能方面取得进一步进展。这些类型的框架的多功能性是那些有趣的特征之一，它也面临着挑战，以产生通过单个结构展示多个属性的适当框架。因此，经过司法选择两种不同类型的配体后，三种配位聚合物{[Cd(1,4-(2-Me)-bix)(glu)]·5(H ₂ O)} _n ( 1 ), {[ Cd ₂ (1,4-(2-Me)-bix)(msuc)]·(H ₂ O)} _n ( 3) 和 {[Zn(1,4-(2-Me)-bix)(msuc)]·(溶剂) _x } _n ( 4 ) 已被合成和表征。这三种化合物以及一种先前报道的结构相似的复合物 {[Zn(1,4-(2-Me)-bix)(glu)]·4(H ₂ O)} _n ( 2 ) 已被用于研究气体吸附、明暗电特性和发光。所有 PCP 都显示出不同的气体吸附（CO ₂、N ₂、H ₂) 和在黑暗和照明条件下的电导率，这表明这些结构显示出多功能性。基于二羧酸酯的灵活性/取代和金属离子的大小，这种设计的结构和合成配合物的测量性质与四种配合物的每个单独框架相关。
